Just spent the last 24 hours installing/reinstalling R5F27 to get schedulesdirect working. Using pvr-350, tv-out works out of the box. Despite setting preset channel to 3 and external channel change command to /etc/irblaster/change_channel.sh, myth does not set the tuner to 3 or use change_channel.sh. When watching tv, all I get is gray noise. By using ivtv-tune to set the tuner to 3, I get the broadcast. And using change_channel.sh, I can tune the satellite box.

This hardware was working on a previous version of knoppmyth (not sure which, from maybe Feb 2006). Luckily I'm installing on a new hard drive so I can just pop the old one back in, but tv listings aren't working thanks to zap2it.

Also not getting sound out from looping pvr-350 rca jacks back into sound card, but haven't really configured that yet.

I had been through the troubleshooting guide and adjusted the buffers on the pvr-350 due to errors in dmesg. I had not seen the R5F27-specific hints, but none of them seems to apply to this situation. The channel frequency table is us-cable as recommended in one of the guides when using an external tuner. The capture card is type MPEG-2 encoder (pvr-x50, pvr-500), default input is tuner1, video device is /dev/video0. There does seem to be a bug in the input priority field of the input connections section as you can't enter a value or tab past that field.

Once I have manually tuned channel 3 using ivtv-tune, the video is great. But I can't change channels through the remote. It looks like it's about to change channel (video pauses), but nothing happens. The irblaster does not blink and the card tuner doesn't change either. So it stays on whatever channel the satellite box is on. I can change the channel using /etc/irblaster/change_channel.sh just fine. If I knew what script/executable mythtv is calling to change channels, I could probably soft link it to change_channel.sh and put ivtv-tune -c 3 in rc.local and be done.

I think this was created when the auto-install asked if I had an IR blaster. BTW, I'm doing a fresh auto-install on that separate drive and NOT doing any type of recovery from backup. Thought it would be easier/safer than trying to fix all of the incompatibilities.

One thing that popped into my head is that the lowest channel populated from schedulesdirect is 7. Don't know if this would prevent tuning to ch 3 (output ch from dish 301).

It did occur to me that being in /etc, it might not be accessible to non-root users. But I ran change_channel.sh as my personal account (jhelms) and it worked fine. Didn't try it with mythtv account, but assumed it would work. I might be able to experiment some more tonight (Monday 10/1). If you think of anything else to look at/try, I'll give it a shot.
